This repository contains the hardware, software, and enclosure CAD for the HotClaps cartridge (and accomanying debugger). It will play any audio through Tiger Electronics' HitClips players.
This is a complete rebuild of my Homebrew HitClips project from 2022.
- Significantly improved audio quality over the original toys (hard to quantify, but the bar was low).
- Space for ~10 minutes of audio, which can be split across multiple files. This can theoretically be extended if you dial back the audio quality further.
- USB Storage interface for dragging/dropping audio files from a computer.
- Web application with tools to convert audio files and print custom artwork for the case. (Source code for web app here)
- The hardware is built around the Raspberry Pi RP2040 microcontroller.
- The firmware is written in CircuitPython, and features an audio driver written in pioasm.
